Question

Happy New Year All,

New with implementing Fragments in Android (and I have seen similar posts but I have not been able to get an answer for my problem), so here goes:

I wish to use SupportMapFragment (referenced from the support library v4) and I have created a class that extends FragmentActivity, called TripSummary.java:

package com.project.locationapp;

import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import android.os.Bundle;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class TripSummary extends android.support.v4.app.FragmentActivity {

private GoogleMap mMap;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = new Intent(this, LocationService.class);
    stopService(intent);
    setContentView(R.layout.activity_trip_summary);

    createMap();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_trip_summary, menu);
    return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    //Content?
    return super.onOptionsItemSelected(item);
}

private void createMap(){
    //if a map has not already been instantiated it'll return null
    if(mMap == null){
        //instantiate map
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        //check it has been instantiated
        if(mMap != null){
            Toast.makeText(this, "map done", Toast.LENGTH_SHORT)
            .show();
            //Manipulate map here (add coordinates/polylines from trip etc etc.)
        }
    }
}

}

Which gets a layout from activity_trip_summary.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<TextView
    android:id="@+id/tripSummary"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="@string/trip_summary"
    tools:context=".Start" />

<TextView
    android:id="@+id/tripDetails"
    android:layout_below="@id/tripSummary"
    android:layout_alignParentLeft="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="@string/awaiting_location"
    tools:context=".Start" />

<Fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:layout_below="@id/tripDetails"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.google.android.gms.maps.SupportMapFragment" />

</RelativeLayout>

AndroidManifest.xml is as follows:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.project.locationapp"
   android:versionCode="1"
   android:versionName="1.0" >

    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

      android:protectionLevel="signature"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>


<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <activity
        android:name="com.project.locationapp.Start"
        android:label="@string/title_activity_start" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service android:name="com.project.locationapp.LocationService" />

    <activity
        android:name="com.project.locationapp.TripSummary"
        android:label="@string/title_activity_trip_summary" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.project.locationapp.Start" />
    </activity>
    <activity
        android:name="com.project.locationapp.ViewTrips"
        android:label="@string/title_activity_view_trips" >
    </activity>
    <activity
        android:name="com.project.locationapp.TripDetail"
        android:label="@string/title_activity_trip_detail" >
    </activity>
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="<-- My Key -->"/>
</application>

</manifest>

The problem I am having in that each time I try to load the activity TripSummary, I get a ‘Sorry! stopped unexpectedly’ dialog and the app crashes.

LogCat:

java.lang.RuntimeException: Unable to start activity                   ComponentInfo{com.project.locationapp/com.project.locationapp.TripSummary}:     android.view.InflateException: Binary XML file line #24: Error inflating class Fragment

I am referencing the google-play-services_lib library (which is also in my workspace) and I also have a copy of android-support-v4.jar in /libs directory within my project.

If you know an answer to my problem, please share!

Thanks in advance.

Answer 1

Please replace:

<Fragment

with:

<fragment

Also, you can get rid of the redundant/incorrect namespace declarations in that element.

Also also, in the future, post the complete stack trace, not just part of one line, to make it easier for people to help you.
